Osteoarthritis is a chronic progressive disease where there is degeneration and loss of articular cartilage that occurs together with new bone formation at the joint surfaces and margins that causes pain and deformity.
The patient experiences pain, stiffness, decreased movement, inflammation and crepitus.
The pain is usually aggravated by pain and relieved by rest.
Macrolide antibiotics are derived from the Streptomycesspecies. These contain either 14-membered (erythromycin [ERM],clarithromycin [CAM], roxithromycin [RXM]), 15-membered(azithromycin [AZM]) or 16-membered (spiramycin, josamycin,midecamycin) macrocyclic lactone rings. They inhibit proteinsynthesis by reversibly binding to the 23S ribosomal RNA (rRNA)in the 50s subunit of the bacterial ribosome. Traditionally,macrolides are used as first-line agents in respiratory, skin,soft tissue, and urogenital infections, and they are also activeagainst gram-positive cocci and atypical pathogens.
Nonsmall cell lung cancer (NSCLC) patients harbouring sensitive EGFR mutations may fare well with the third-generation tyrosine kinase inhibitor osimertinib as an upfront therapy, with the results of a network meta-analysis showing that the drug tops other currently available options in terms of progression-free survival and tolerability.
